Mullateaduse õppetooThe current study was conducted to determine the potential for some antibiotics to be taken up by food plants from soil fertilized with manure, sewage sludge or its compost containing antibiotic residues. The plants (potato – Solanum tuberosum L., carrot – Daucus carota L., and wheat – Triticum aestivum L.) were cultivated in greenhouse under natural light conditions in the presence of three fluoroquinolones (ciprofloxacin, ofloxacin, and norfloxacin), and two sulfonamides (sulfadimethoxine and sulfamethoxazole). The uptake of antibiotics was demonstrated from two different soils (loamy and loamy sand). The concentrations of each antibiotic in soil were 0.01, 0.1, 0.5, 1.0, and 10 mg kg–1. The antibiotics were extracted from the plants using the liquid extraction (LE) and cleaned up by the solid phase extraction (SPE). The extracts were analyzed by liquid chromatography electrospray ionization tandem mass spectrometry (LC-ESI-MS/MS). The accumulation range depended on antibiotic con- centration in soil, chemical properties of the antibiotic, soil type, plant species and parts (overground or below-ground). At soil concentrations of 10 mg kg–1 antibiotics accumulated in edible parts of most plants in amounts, which exceeded their maximum residue levels (MRL) set for food of animal origin – 100 μg kg–1. The highest average content of antibiotics was detected in potato tubers and carrot roots grown in the loamy sand soil – 3897 μg kg–1 and 3400 μg kg–1 sulfamethoxazole. Plants accumulated antibiotics (ciprofloxacin and ofloxacin) from soil even at soil concentration of 0.01 mg kg–1. Mostly the highest concentrations of antibiotics were detected in below-ground parts of the plants grown in the loamy-sand soil.
